bone-targeting prodrug has been designed, synthesized, and evaluated for in vitro and in vivo metabolic stability, in vivo tissue distribution, and rates of release of the active constituents after binding to bones through the use of differentially double-labeled derivatives. The conjugate (general structure 7) embodies the merger of a very potent and proven anabolic selective agonist of the prostaglandin EP4 receptor

receptor antagonists that have been investigated for the treatment of human obesity. To further understand their biotransformation profiles, radiolabelled and stable-labelled products were required. This paper describes the utility of [14 C]1,1-carbonyldiimidazole as a radiolabelling reagent for the syntheses of carbonyl-labelled [14 C]BMS-725519, [14 C]BMS-811064, and [14 C]BMS-812204. The syntheses of

the diol 84 with the naphthoicacid 13 followed by selective cleavage of the chloroacetate protective group in situ to furnish the naphthoicacid ester 85 in 80% yield; and elimination of the tertiary hydroxyl group within intermediate 88 using the Martin sulfurane reagent (79% yield). Reductive transposition of the product epoxy alcohol (58) then formed neocarzinostatinchromophore aglycon (2, 71% yield)

Reaction of N-(trimethylsilyl)imidazole (2) with phosgene-14C in toluene afforded 92 w/w % pure (1H NMR) 1,1′-carbonyldimidazole-1-14C (3) in near quantitative yield. Activation of MPEG-amine 4 by reaction with 3 in dichloromethane afforded intermediate 5 in situ. Further reaction with hydrazine in toluene at 50°C and reprecipitation from 2-propanol afforded crude 1 (81%). A two-step chromatographic purification of this material followed by reprecipitation from 2-propanol gave MPEG-semicarbazide linker1. This material had a chemical purity estimated at 98%, a radiochemical purity of 95%, a specific activity of 7.7 μCi/mg (37.6 mCi/mmol) and a number-average molecular weight of 4885 (1H NMR).
